Shoulder Denervation for Post Mastectomy Irradiation Shoulder Pain

Shoulder individual nerves thermal RF technique: The patient will be put in the sitting position, monitored with electrocardiography, pulse oximetry, and non-invasive blood pressure. after disinfection A high-frequency linear transducer (10-15 Hz) will be placed parallel and cephalad to the spine of the scapula. The probe will be moved from cephalad to caudad until the trapezius and supraspinatus muscles were identified. The suprascapular nerve will be identified as a hyperechogenic structure in the suprascapular fossa deep to the superior transverse scapular ligament. A 10 cm radiofrequency needle, with a 10 mm active tip, will be inserted in plane with the ultrasound beam and advanced to reach the proximity to the nerve. A nerve stimulator was used as an additional nerve-finding modality.

Patients will receive conservative treatment Acetaminophen (paracetamol 1000 mg tid and pregabalin (lyrica) 75 mg bid; can be increased to 150 mg bid, oxycodone (oxynorm) 10mg IR PRN.
